A neurotransmitter. Acetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system. It is generally not used as an administered drug because it is broken down very rapidly by cholinesterases, but it is useful in some ophthalmological applications.
A neurotransmitter that triggers increased focus, enhanced calmness, and decreased symptoms of anxiety; also helps the brain process information.
A neurotransmitter in the brain, where it helps to regulate memory, and in the peripheral nervous system, where it controls the actions of skeletal and smooth muscle.
One of the chemical neurotransmitters normally present in many parts of the body that enables nerve cells to signal each other.
ACH is a key transmitter involved in attention and memory and it decreases as we age and in Alzheimer’s Disease. It’s made from choline, which is partly gained from diet, so increasing choline in the diet (soy and quinoa are choline-rich plants) may increase ACH levels.
A neurotransmitter that binds to nicotinic (nACh-R) or muscarinic (mACh-R) receptors.
Neurotransmitter substance that transfers nerve impulses across neuromuscular junctions, stimulating contraction of muscle fibers.
An acetic acid ester of choline that is normally present in many parts of the body and functions in the transmission of nerve impulses.
A substance released from nerve endings, which allows nerve impulses to move from one nerve to another or from a nerve to the organ it controls.
A neurotransmitter released by a calcium-dependent process in response to the arrival of an action potential. Acetylcholine initiates changes in ion permeability that occur at the neuromuscular junction. Acetylcholine is hydrolyzed by acetylcholinesterase to choline, which is then reused.
Acetylcholine is a neurotransmitter released by nerve endings at the neuromuscular junction in response to an action potential.
A neurotransmitter of the central and peripheral nervous system.
A neurotransmitter in the somatic and autonomic nervous systems; principal synapses using acetylcholine include the skeletal neuromuscular junction, autonomic ganglia, and certain pathways in the brain.
Chemical that is an important neurotransmitter in the body, functioning in the transmission of impulses between nerve cells and between nerve cells and muscle.
The acetic acid ester of the organic base choline: the neurotransmitter released at the synapses of parasympathetic nerves and at ‘neuromuscular junctions. After relaying a nerve impulse, acetylcholine is rapidly broken down by the enzyme ‘cholinesterase. ‘Atropine and curare cause muscular paralysis by blocking the action of acetylcholine at muscle membranes; ‘physostigmine prolongs the activity of acetylcholine by blocking cholinesterase.
An acetic-acid ester of the organic base choline, acetylcholine is one of the substances which mediates the transmission of nerve impulses from one nerve to another, or from a nerve to the organ it acts on, such as muscles. It acts on both muscarinic receptors (blocked by ATROPINE and responsible for ganglionic and parasympathetic transmission and also for sympathetic innervation of sweat glands) and nicotinic receptors (responsible for the transmission of nerve impulses to muscles and blocked by curare, thus causing paralysis). Acetylcholine is rapidly destroyed by cholinesterase, an enzyme present in the blood. anticholinergic drugs such as physostigmine prolong the action of acetylcholine.
An ester of choline that is the neurotransmitter at somatic neuromuscular junctions, the entire parasympathetic nervous system, sympathetic preganglionic fibers (cholinergic fibers), and at some synapses in the central nervous system. It is inactivated by the enzyme cholinesterase.
The neurotransmitter used by all preganglionic neurons of the autonomic nervous system as well as the postganglionic neurons of the parasympathetic branch of the autonomic nervous system.
The chemical messengers discharged by the nerve cells belonging to the parasympathetic sector of the autonomic nervous system.
It refers to a specific chemical known as a neurotransmitter, which serves the purpose of stimulating nerve cells.
Acetylcholine, a specific type of neurotransmitter responsible for transmitting messages between nerve cells or between nerve and muscle cells, exists ubiquitously at nerve-muscle junctions and numerous other locations within the nervous system. The effects elicited by acetylcholine are referred to as cholinergic actions, which can be counteracted by anticholinergic medications.
A neurotransmitter that attaches to either nicotinic (nACh-R) or muscarinic (mACh-R) receptors.
